Solving Equations Involving Vertical Angles and Linear Pairs

Solve equations with angular relationships - Video & Lesson Transcript

We will examine in this unit how to find unfamiliar phenomena in geometrical shapes. We show with the help of samples how angular relations work with algra to find a solution. Now, how about a mixture of Algebra and geometrics? Indeed, a very beautiful mixture of Algebra and geography happens when we are identifying geometrical angular relations and then expressing strangers with equations given by the Algebraic.

We will consider the angular relations that are supplemental angles, supplemental angles and vertical angles. Fact: Additional angles are added to 180o. That means if we know one of two additional angles, we can simply compute the other one. This example shows the angles of 150o and x additionally. This means the x equals 30°.

Let us modify the alignment of the lines and give the unfamiliar angles an algraic look. For x, the step to solve: I. D.: I: I: Define the angular relationship: There is a linear line, and we see 160o and 2x are additional angles. Compose an equation: Thus x = 15 and the unidentified corner 2x = 30 o.

They are still the same steps: Define the angular relationship: Angles of sixty degrees and four times are additional. Compose an equation: SOLUTION for the unknown: So x = 30 and the unfamiliar corner is 4x = 120o. As we continue our mixture of geography and imagery, we consider the ratio of complimentary angles.

The small rectangle in a character indicates an angular of 90°. Fact: Supplementary angles sum to 90°. To see a small rectangle in a character is a hint to search for complimentary angles. So we see that x and x50 complement each other. I. D.: I: I: Define the angular relationship: Angles of 35- and 2x-5 are complimentary.

Compose an equation: SOLUTION for the unknown: So x = 30 and the unfamiliar corner is 2x - 5 = 55-0. There' another succulent angular relation to consider. At the intersection of two intersecting axes, the axes make pairs of identical angles. Vertical angles are these kinds of angles.
